Microdetemination of nitro and nitroso groups in aliphatic and aromatic compounds, especially in nitro-arginines
Microchimica Acta - 1980
Tóm tắt
A novel microanalytical method is described for the quantitative determination of nitro and nitroso groups in aliphatic, aromatic and nitro-arginine compounds. During decomposition by pyrolysis in a stream of oxygen, nitrogen oxides and decomposition products containing nitrogen were formed from the nitro and nitroso groups of the substances studied. These were transformed into nitrogen dioxide by a lead dioxide packing. The nitrogen dioxide was absorbed in acetic acid and determined iodometrically after deoxygenation with carbon dioxide. A statistical evaluation of the results for ten aplihatic and aromatic compounds and eight nitro-arginine compounds showed the error did not exceed ±0.3% absolute.
